Reciprocity

She liked his paintings. She liked what he painted and she liked how he painted. She liked him, and she wrote to him to tell him how much she liked what he painted and how he painted, and to show him a few of her own paintings. She was pleasantly surprised when he wrote back to her, but bitterly disappointed when he didn't like her paintings as much as she liked his. She didn't like him after that, nor what he painted, nor how he painted. This surprised him, since what he painted and how he painted had not changed; he didn't know he had to like another person's paintings for them to like his own.
